Multiple value selection

System

Hi,

I have the following dropdown.

<select name="branchmenu" multiple="true">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>

I have the follwoing code in perl
$val= $cgi->{'form'}{'branchmenu'};

when i am selecting single value it is working perfect.

Iwant to select multiple values If i select multiple values in that time above perl line it is displaying ARRAY(09XXCC) some thing like this.

any body help me to fix this error.

Thanx in advance

Could you please attach the script or atleast copy the portion of the script where you are trying to *print* or *use* the values?

Thanks!

Thanx for your reply.

I am using that value as input to other perl program like this

abc.ipl $val

$val from the dropdown if i have one it is working.If i selected multiple values i have to repeat above loop three times.I am not able to get the data It is displaying like ARRAY(withsomehexavalue).

Thanx

OK, so that is the way it is supposed to work because of it being not an array. And if you need a scalar value of complete selection in one, then you could have the foreach loop through and concatente using "." operator. That way this lopp will fetch all values one by one and will construct a scalar variable for you that you could pass to the program.

my $newvar;
foreach my $myvar ($cgi{'form'}{'branchmenu'})
{
$newvar .= $myvar;
}

In the above example, $newvar woul dhave the complete list of values as a scalar.

Hope this helps!

Thanks for your response once again
Still it is printing this value
Array(0x10c499c).
In the for loop it is not printing anything.

1. The example that I gave didn't have any print statement in for loop. It was just an example of how you could get a scalar value. Did you modify it to have your variable names?

2. Could you please post the code that you are using. If possible please attach the script in your post.

I need to see how you are trying to use the variable. This seems like an error with logic for your script.
Thanks!

$val= $cgi->{'form'}{'branchmenu'};

After that, try:
if (ref($val) eq "ARRAY"){
$val = join(",", @$val);
}

The above is off the top of my head, untried because I'm tired (sorry)

my $newvar;
foreach my $myvar ($cgi{'form'}{'branchmenu'})
{
$newvar .= $myvar;
}

This is invalid syntax. It appears that $cgi{'form'}{'branchmenu'} is an arrayref, judging from the value it's printing out being ARRAY(blah). So your code would need to look something like this:

my $newvar;
foreach my $myvar (@{$cgi{'form'}{'branchmenu'}})
{
$newvar .= $myvar;
}

Of course, all this does is munge all the values together, if that's what you want to do. I think ghoti's response is the better way to go.

The reason that it "is displaying ARRAY(09XXCC)" is because when you select multiple elements of a SELECT object, the perl library that Interwoven uses to parse the CGI patameters retruns a reference to an array holding all of the selected values.

When you only select one value, you get it back in a scalar.

That is why people have provided you with code snippets intended to show you how to iterate over the array reference.

if you just want all of the selections to end up in a scalar, for printing. You can create a comma separated list in a scalar.


$val= $cgi->{'form'}{'branchmenu'};
if (ref($val) eq "ARRAY") {
      print join(', ' , @{$ref});
} else {
    print $val;
}

Just a nit - sorry:

$val= $cgi->{'form'}{'branchmenu'};
if (ref($val) eq "ARRAY") {
print join(', ' , @{$ref});
...

That should be @{$val} (or just @$val) not $ref

You are correct.

Something to keep in mind...

I assume this question arose becaue the original poster was doing this in a cgitask script. However, according to the WF Developer's Guide (on pg. 127 of the 5.5.2 version) you can have multiple select lists in your TAG_info variables as well. However, there is a shortcoming (filed as bug #23980) that if you try to do this, therefore causing your TAG_info value to be an array rather than a scalar, and then you try to read this workflow variable (using the iw_setwfarg prefix) in an external script, you will not be able to read it as an array. In fact, it will be a scalar with the value "ARRAY(0x2fcb0)" or something to that effect. This is not an arrayref, but a string with those exact characters. The TAG_info variable in your wft is stored as an array, but you can't look at it using WFworkflow::GetVariable in a script.
